Problems with Classloader / Classpath during deploying a WAR

[vbaghdas]

Hello,

maybe somebody can hlp in following issue.

I am deploying a test archive via MavenImporter in following way:

	{code}
	public static WebArchive createServiceDeployment() {

WebArchive serviceArchive = ShrinkWrap

.create(MavenImporter.class)

.configureFromFile(new File("C:/Users/vbaghdas/.m2/settings.xml"))

.loadPomFromFile("../dsuite-parent-demo-service/dsuite-parent-demo-service-impl/pom.xml")

.importBuildOutput()

.as(WebArchive.class);

System.out.println(serviceArchive.toString(true));

return serviceArchive;

}

{code}

During deploying folowing Exception happens:

Caused by: java.lang.ClassCastException: org.springframework.context.annotation.ScopedProxyMode cannot be cast to org.springframework.context.annotation.ScopedProxyMode

I checked my classpath - I have only 1 version of problematic spring-context jar, but it appears twice within classpath, as, by the way, each of other jars added to the classpath. Could that be the problem?

Thank You and regards,

Sorry, I checked my classpath - I I have only 1 version of problematic spring-context jar, and I have it indeed only once in the classpath - so I uderstand the problem even fewer now ...

[vbaghdas]

Ok, actually I found the way to exclude doubled "boarding" of spring libs ny adding following snippet into arquillian. xml:

{code}

<extension qualifier="spring-deployer">

        <property name="auto-package">false</property>

</extension>

{code}

But now I'am struggling with the next problem:

IntegrationDemoAuthenticationConfiguration is a spring configuration class file with defined beans within it. My test class bind it by doing

@SpringAnnotationConfiguration(classes = { IntegrationDemoAuthenticationConfiguration.class, ...})

[vbaghdas]

I found the reason for the problem.

The Java Spring configuration classes, which are added to the test class via @SpringAnnotationConfiguration, should be also added to the test archive via addClasses()

Hi,

today i did stumble upon a similar problem. i have a web app that includes the jersey jax-rs library. When run under the junior arquillian runner there seems to be a conflict of the jersey classes existing in the war file, i.e. Tomcat web app class loader and in the maven/plexus class world class loader. Trying to us the jax-rs client in the arquillian test @runasclient and in the web app itself crashes the we app. I wonder how to solve this problem.

the arquillian at runner should probably different classloaders for the tomcat embedded container and the execution of the client side tests.

maybe there is a way to exclude the maven dependencies from the resulting war file or from the junior classpath. I tried to use the maven fail safe plugin option excludesystem classloaders but without a good result. I'll investigate this problem deeper tomorrow.

just my 2 cents
